Benchmark: for lef of OR for var of OR for var length - v3

HTML Preparation code:

<div class="list-container">
  <div class="list-item"></div>
  <div class="list-item"></div>
  <div class="list-item"></div>
  <div class="list-item"></div>
  <div class="list-item"></div>
</div>

Script Preparation code:

var $allItens = document.getElementsByClassName('list-item');

Tests:

for lef of
for (let $item of $allItens) { console.log($item); }
for var of
for (var $item of $allItens) { console.log($item); }
for var(out) length
var i = 0; for (i; i < $allItens.length; i++) { console.log($allItens[i]); }
for var(inside) length
for (var i = 0; i < $allItens.length; i++) { console.log($allItens[i]); }
for var(out) length(out)
var i = 0, l = $allItens.length; for (i; i < l; i++) { console.log($allItens[i]); }
for var(inside) length(inside)
for (var i = 0, l = $allItens.length; i < l; i++) { console.log($allItens[i]); }
for var(out) item check
var i = 0; for (i; $allItens[i]; i++) { console.log($allItens[i]); }
for var(inside) item check
for (var i = 0; $allItens[i]; i++) { console.log($allItens[i]); }
